MILWAUKEE (January 26, 2004) - The new JIMS Twin Cam Race Kit, available exclusively through Harley-Davidson dealers, is a complete component package designed to serve as a solid foundation for racers seeking big horsepower and displacement. The engine kit is designed to fit Harley-Davidson Dyna and FL models originally powered by the Twin Cam 88 engine.

This 120-cid package, developed by JIMS of Camarillo, Calif., pumps out 125 rear-wheel horsepower at 6200 rpm and 121 ft. lbs. of torque at 3750 rpm on 91 octane pump gasoline. This engine kit was developed as a result of a license Harley-Davidson granted to JIMS for use of some Harley-Davidson Twin Cam intellectual property.

The JIMS Twin Cam Race Kit is based on a 356-T1 aluminum crankcase with enough case material to support a bore size up to 4.800 inches. The crankcase is delivered with the lower end fully assembled. All other components required to complete the engine are included, including JIMS forged pistons, JIMS 4.125-inch bore cylinders and JIMS cylinder heads with matching stud spacing. The cylinder heads and cams were developed in conjunction with the Harley-Davidson Screamin' Eagle group. Stock rocker covers are CNC relieved by JIMS to clear special valve springs. Fuel is delivered by a Screamin' Eagle Pro Super Bore 51mm carburetor and matching intake manifold. A Screamin' Eagle Pro Adjustable MAP Ignition System handles timing and spark (engines for '04 models use the Screamin' Eagle Pro Ignition Race Tuner Kit).

Experienced technicians can finish the assembly of the JIMS Twin Cam Race Kit in just four to six hours using detailed instructions included with the kit. The kit is offered uncoated, and in black or silver powdercoat, color-matched to stock Harley-Davidson transmissions. Suggested retail price in the United States is $7,999.95. The JIMS Twin Cam Race Kit engine is for racing use only. Softail cases and EFI kits are not available.
